Inexpensive device to reduce surgical light exposure

Area of Science:

• Ophthalmology
• Surgical Innovation
• Biomedical Engineering

Background:

• Intraocular surgery requires intense illumination from operating microscopes.
• Prolonged light exposure poses a risk of retinal phototoxicity to patients.
• Existing protective measures may be costly or complex.

Purpose of the Study:

• To describe an inexpensive, disposable device for reducing light exposure to the retina during intraocular procedures.
• To present a novel method for creating a retinal light shield from readily available materials.

Main Methods:

• A disposable cap was fabricated from a brown, rubber surgical glove.
• The cap was created using a 9.0 mm corneal trephine to cut a circular shield.
• The device is designed to fit over the surgical site, reducing light intensity.

Main Results:

• The fabricated rubber cap effectively shields approximately 75% of light.
• The device is inexpensive, easy to prepare, and simple to use during surgery.
• The method provides a practical solution for mitigating retinal phototoxicity risks.

Conclusions:

• This low-cost, disposable rubber cap is a viable option for surgeons to minimize retinal light exposure.
• The device addresses concerns regarding potential phototoxicity from surgical microscopes in intraocular surgery.
• Further studies could evaluate long-term efficacy and patient outcomes with this protective measure.
